I thought Cummins was a diesel engine and cumming(s) had to do with... . 

My understanding was that as stated above Dodge built motors and many auto parts and yes even bikes. Ford was a large purchaser of Dodge parts. Then the Dodge brothers decided to build their own cars. Ford never owned them. They started Dodge Brothers Motor Vehicles. Then one day a guy named Walter P Chrysler purchased the company in the mid 20s. Another little factoid, Dodge built and sold the first civilian four wheel drive truck. It was called the Dodge Power Wagon.Actually... Dodge was created by the Dodge brothers. They started building bicycles. Then they started building motors for Ford. As time progressed they ended up building four wheel drive systems for Ford. Eventually... Ford sold them. The rest is history.
